On October 2, 1987, the Attorney General forwarded to you his serious objection to the acceptability of the methodology einployed and the res alts reached by the Applicants in their recent test of the average summer daytime ambient sound pressure levels in certain areas of Merrimac, Massachusetts, i In that letter we enclosed an affidavit from Gregory C. Tocci, of the acoustics consulting firm of Cavanaugh Tocci Associates, l in which Mr. Tocci briefly described the results of an l extensive series of ambient sound pressure measurements his firm collected recently over the course of five days in the l three areas in Merrimac in which the average summer daytime ambient sound pressure levels are in dispute. In forwarding this affidavit to you we noted that, because of the due date for our comments, Cavanaugh Tocci Associates had not yet completed its full report on all the measurements it had taken. We then requested leave to submit the full report within twenty-one (21) days.

We believe this report demonstrates beyond a reasonable 1 doubt that in-two of the. disputed areas of Merrimac the "10dB above backgrohnd" standard of'NUREG-0654 and FEMA-REP-10 is not met.

As we urged in-our letter-of October 2, 1987, we respectfully request.that the Appeal Board admit the Attorney General's Merrimac siren contention and remand it to.the Licensing Board for appropriate proceedings. .

l INTRODUCTION l

Cavanaugh Tocci Associates, Inc. has been retained by the f I

Department of the Attorney General of the Commonwealth of l Massachusetts to conduct ambient sound level measurements at f I

locations in Merrimac, Massachusetts indicated in the Siren j System Coverage Map (Figure 2.1-3) of the New Hampshire Radiological Emergency Response Plan 1 as being outside the 60 dBC coverage zone.

We have been instructed by the Department of the Attorney General that we are to consider siren sound levels outside the 60 dBC contours of the Siren System Coverage Map to be 50 dBC.

According to NUREG-0654/ FEMA-REP-1: Criteria for Preparation and Evaluation pf,. Radiological Emeroency ]Lesnon s e P_Jans and Preparedness ID Eupport o_f Nuclear Power Plants, the siren sound pressure level should be at least 10 dB above the ambient sound level. Therefore, in siren coverage zones where the siren sound level may be as low as 50 dBC, the ambient sound pressure level should not exceed 40 dB. It is the aim of this work to ascertain whether or not ambient sound levele in the 50 dBC siren coverage zones exceed 40 dB.

Locations selected for monitoring in Merrimac, MA were all residential dwellings at the following addresses:

. 23 South Pleasant Street

. 16 High Street l

l

. 25 River Road i

. 64 Bear Hill Road 1 ,

i

K

. Houses selected,were not solitaryLdwellings, but were each part' q

of groups of-houses'shown in the siren coverage map.as falling-outside the 60 dBC coverage zone. Ambient sound levels measured at each location . are -representative 'of ambient sound levels at l

> other houses in the vicinity'of each. measurement location.

' SOUND-LEVEL DESCRIPTORS Ir In the. preceding' introduction, there occurs a discrepancy between:

'descriptors used -in the evaluation o f- siren sound. This-discrepancy. revolves around the use'of c-weighted sound level.for

~

siren sound and un-weighted sound level for the required margin j i

between siren sound and ambient sound. j i

In quantifying siren sound level, some imprecision in sound level.  :

descriptor and. method of siren sound measurement can be tolerated. This is because siren sound is presumed constant in

level- and comprised. of sound energy in one or more frequency-bands. Normally, siren sound is comprised of sound energy at a- <

fur.damental frequency and sound energy at the first harmonic (fundamental frequency in Hz x 2). Typically, at least 90% of a siren's sound energy is concentrated in a very narrow band of  !

frequency about the fundamental with most of the rest of the sound energy falling in a narrow band at the first harmonic, and l minute amounts of sound energy at higher harmonics. By .

I quantifying sound level using C-weighting (uniform sensitivity to sound energy between 20 Hz and 20,000 Hz, i.e. uniform I

sensitivity over the entire frequency range of human audibility),

results. This is especially true w h an iro mental sound.which .\

exhibits both short . term and long - term variations. Short term r

.I c .

variations are exemplified by, changes in sound level produced by passing -. vehicles on a highway. . ; Long term variations in sound level, in this same example, would correspond to variations in traffic volume between rush hour and early morning hours.- This example illustrates the kinds of features that characterize ambient sound and which must be.roflected by environmental sound descriptors used.

Generally, ambient sound ris produced by distant traffic, wind blowing through foliage, and miscellaneous neighborhood activities. Ambient noise measurement does not necessarily. imply the use of any specific type of noise descriptor, method of tima averaging, nor duration of noise measurements. In order t.o l uniquely quantify ~ ambient sound level, an environmental <nalse descriptor must' indicate:

time interval over which sound was measured;

. any frequency weighting or filtering used;

. sound level meter averaging time;

. sound level samole averaging or processing method.

Withouti' the specifice,tif on. of all four.of the above features, a j-3p - i c measurement of ambient sound would be ambiguous.

1 xi t l Prior to our conducting ambient sound -level measurements, we investigated a number of publications _ and reports pertinent .to -

the Seabrook Emergency Siren System in order to characterizethe

.four above-mentioned' features of'descriptors needed to quantify

[.f' .

b ambient sound level.- .With respect to each feature, our review of

.g pertinent materials has indicated the following:

. Time Interval Item 3f of NUREG-0654 indicates that sirens should achieve:

a sound pressuru level 10 dB above the " average daytime ambient background" sound pressure level in the frequency band sontaining the siren signal frequency. Similarly, i FEMA-REP-10. refers to a " daytime average."

4 t Daytimo generally refers to the period beginning at 7:00 SAM.and extending t'o 6:00 PM or 10:00 PM depending on the de ;criptor or criteria being used. It is not clear I

whether these publications intend measurement of sound l l

data continuously over the " daytime" period or measurement  !

of sound ' data over one or more short intervals during the 1

"daytdme." Normally, it is preferred to divide a daytime q

\

period into small time intervals in order to obtain some j perspective on how ambient sound varies throughout the 4

^

minute intervals provides some perspective on the y

variation of ambient sound over the 15 minute and 30 l minute intervals used by Wyle and HMM respectively. More t

importantly, Cavanaugh Tocci Associates, Inc. has measured l ambient sound pressure levels continuously in 5 minute intervals at all four above indicated locations for l 1

, > substantial periods between Wednesday, September 23, 1987 and Sunday, September 27, 1987. This has allowed us to 4

p

[ clearly evaluate ambient sound level variations on a hour-f to-hour, day-to-day, and weekday-to-weekend basis, f,

Although our measurement activities do not document seasonal ambient sound level conditions, sound levels were conducted on lightly breezy days with trees fully foliated. It is presumed the ambient sound levels during the summer with the same weather conditions could be  !

r noisier because of insect sound. It is also presumed that ambient sound levels during the winter with snow cover would be lower than measured in September. Hence, ,

1 measured ambient sound levels measured by our firm at the four locations in Merrimac probably do not reflect unusually quiet or unusually noisy conditions.

. Filterina 2

As noted above, Item 3f of NUREG-0654 indicates that 6

i t__

-4.

ambient sound levels are to be measured in the frequency l

. band containing the siren tone. Neither.this nor FEMA-REP-10 3 specify the frequency bandwidth appropriate for filtering ambient sound. We agree with reasoning presented by both Wyle Laboratories 4 and HMM Associates 7 that one-third octave band filtering is appropriate for siren audibility studies. .As explained by Kryter6 , human perception of puretones is related to the puretone ' level relative to the masking (ambient) level in the one-third octave frequency band containing the puretone frequency. j Based on the HMM Associates letter dated March 11, 19875, we have understood that the siren tone occurs at 680 Hz  ;

and therefore falls into the 630 Hz one-third octave band frequency band.

-i

. Meter Averacina Time  !

Nowhere is there given an appropriate meter averaging time. Meter averaging time is a measure of the response ,

of a sound measurement instrument display to variations in i sound pressure level. Current .etandards for sound measurement instrumentation define two meter averaging times: SLOW (1 second averaging time) and FAST (0.05 sec.

averaging time). Unless there is specific interest in high transient sound levels, SLOW sound level meter averaging is nearly always used in environmental studies.

It is presumed that data presented by Wyle and HMM were ,

7

gathered using SLOW sound . level motor avaraging and' that l

'it ' is ' the intention of pertinent guidelines - that . SLOW sound level meter averaging be.used. Ambient sound level measurements conducted by Cavanaugh Tocci Associates, Inc.

used. SLOW sound level meter averaging. Actually, for the sound level descriptors of concern, little difference is expected between the use of SLOW and FAST sound level meter averaging time.

Sound Level Samole Processina

~

Regulations and other materials reviewed relevant to siren l audibility assessment quantify ambient sound as percentile ,

exceeded sound pressure levels. Two specific percentile levels have been cited: The Lg o, i.e. the sound pressure {

level exceeded 90% of a stipulated time interval and sometimes referred to as the background sound level, and i

the L 50, i.e. the median sound level or the sound level  !

exceeded 50% of a stipulated time interval. Part of the j confusion in this study is that the time interval for these percentile levels is not specified. So important is the time interval that current standards require expressing these descriptors as Lgo (30 min.) or L 50 (15 min.) for example. Among the descriptors measured by Cavanaugh Tocci Associates, Inc. are the Lgo (5 min.) and the L 50 (5 min. ) in the 630 Hz one-third octave band as discussed.

NUREG 0654 does mention " daytime average background sound 8

e\,.'

level.'"2 This-is confusing since average.usually. Implies 50th percentile sound levels, whereas background - implies .

90th percentile ~ sound . levels. In our studies . we : have-

opted - to use 50th percentile sound : levels as recommended'

. by HMM.. Associates in 'their Final' Design Report ' for the Seabrook Siren! System dated January 19844

)

'In ~ summary, Cavanaugh Tocci Associates, Inc. has carefully reviewe'd~ existing' standards and Seabrook siren studies to develop-an ambient' sound level measurement plan which responds as'best as

~

possible to the intentions of siren audibility regulations. In t

as far as we can, we'.have adopted the methods and reasoning of (

. previous. investigators, and where we felt necessary, we - have. ,

'devel'oped and' expanded the~ measurement plan beyond those of f earlier. investigators.

l AMBIENT SOUND LEVEL MEASUREMENTS 1

.)

1 Two of the four systems used to monitor sound levels at the four

, .i above mentioned. residential locations included 1" microphones outfitted with windscreens and cable connected to Quest Sound

~

Level Meters outfitted with one-third octave band filters set to i

630 Hz. The output signals from the Quest Sound Level Meters were analyzed by Digital Acoustics DA607P Community Noise Analyzers which produced strip chart records in 5 minute intervals.

i l:

A third system used a 1" GenRad Microphone and Preamp which was outfitted with a windscreen and was cable connected to a GenRad l

9

f 1654-A Sound and Vibration Analyzer. The analyzer is equipped-with internal third octave band filters and was set to the 630 Hz one-third-octave band. The signal from this device was analyzed-by a Digital Acoustics 607P Community Noise Analyzer which was _l I

also set to produce a strip chart record of sound level descriptors in five minute intervals. q A fourth instrumentation system used a Bruel & Kjaer 1" Microphone and Preamplifier outfitted with a windscreen and

' connected to a Bruel & Kjaer 2231 Sound Level Meter outfitted with a one-third octave band filter set and statistical-analysis module. This device was capable of directly measuring environmental noise descriptors which were printed using a ,

Okidata dot matrix printer. This instrumentation system measured -l l

5 minute noise descriptors and printed them every 5.40 minutes.

All devices were calibrated immediately prior to measurements i with a GenRad 1562-A Sound Level Calibrator or a Bruel & Kjaer Type 4230 Sound Level Calibrator or a Quest CA-22 Sound Level Calibrator. Calibration was confirmed during measurements and immediately following the conclusion of measurements. All four instrumentation systems conform with ANSI Standard S1.4 for Type _l 1 Precision Sound Measurement Instrumentation. A complete listing of all instrumentation used at all four locations is provided in Appendix A. ]

\

U Air temperature during all sound measurements ranged between 38 F 10 4

1

cnd 68 F. Estimated wind velocities at the microphones generally ranged from 0 to 15 mph. Appendix B contains a weather summary for days during which sound measurements were conducted.

Measured 630 Hz one-third octave band L go (5 min.) and L 50 (5 min.) sound levels are shown plotted in Figures la through Figure 4b for each of the four locations. An actual listing of measured L go (5 min.) and L 50 (5 min.) 630 Hz one third octave band ambient sound levels is given in Appendix C.

At Locations 1 and 2, there were gain changes made in the Quest Sound Level Meters as a precaution against meter overloading during noisier periods. Although this helped to ensure measurement accuracy during noisier daytime periods when the ambient sound levels were between 40 and 50 dB, this change increased the instrumentation system noise floor so that the early morning (12 midnight to 5 AM) sound levels are shown to be higher than actually occurred as indicated in Figures la through 2b. At all locations, especially Location 3 - 25 River Road, some data was lost because of instrumentation malfunctions.

CONCLUSIONS Based on measured data in Figures ib, 2b, and 3b, and on data in i

Appendix C, the 630 Hz one-third octave band L50(5 min.) sound j levels at Locations 1, 2, and 3, outside the 60 dBC siren I

coverage zone, are significantly, and for extended periods of time, above 40 dB. This would be true for any of the sound descriptors previously used by other investigators: 5 minutes, 11 l l

1  :

r 15 minutes, and 30 minutos. It should also be noted from data' in

' Figures la, 2a, and frotjdata'in' Appendix C, that the 630 Hz one-2-

third octave' band L9o(5 min.) sound levels at Locations ' l- and r t

. are also above 40 dB. l I'

It is therefore concluded that the required 10 dB siren signal l margin over ambient may not be met in certain areas of Merrimac, 1 MA represented by' Location 1, 2, and 3, 1
